Figure 3. Cumulative soft tissue volume in relation to zygomatic arch and lateral orbital rim (red = temporalis muscle, orange = fat, black = combined total). (A) The maximum temporalis muscle volume predicted is 20.4 mL at a length of 55.6 mm along the zygomatic arch and the maximum fat volume predicted is 10.4 mL at a length of 60 mm with a combined total volume of 30.8 mL. (B) The maximum temporalis muscle volume predicted is 19.2 mL at a length of 89.4 mm and the maximum fat volume predicted is 10.3 mL at a length of 44.2 mm along the orbital rim with a combined total volume of 29.5 mL. (C) Total combined volume along the zygomatic arch axis (green) and the lateral orbital wall axis (purple). The discrepancy in volumes along the zygomatic arch and orbital axes occurs due to variation in individual tissue perimeters.
